From a fisheries management perspective, what I would say is that as we noted earlier, the science is ongoing in identifying what those other factors may or may not be. I wouldn't want to speculate on what they would be.
I can say that for the stocks in the Maritimes Region, we are, as I'm told in my notes, undertaking a management strategy evaluation of the stocks.
This is a scientific process that creates a model, and we can test various management approaches to see what the outcomes might be. It's a growing area within fisheries management globally, and it seems to be an approach that is quite effective at finding good management strategies to manage challenging stocks.
